MECHANISM FOR LOCKING BATTERIES 0F DOORS.

Specification of Letters Patent. Patented Ma 36; 1915 Application filed December 26, 1912. serial No. 788,672.

To all whom it may concern:

Be it known that I, ALBERT A. PAGE, a citizen of the United States, residing at East Haven, county of New Haven, and. State of Connecticut, have invented certain new and useful Improvements in Mecha-' nism for Locking Batteries of Doors, of 1 which the following is a full, clear, and exact description.

This invention relates to mechan sm for locking batteries of doors such as exit doors of school houses, theaters and similar buildmechanism illustrate fi y improvements are particularly applicable to mechanism'for simultaneously looking two or more pairs of swinging doors arranged in a row, but they are also applicable to mechanism for locking three swing ng doors, and certain features of the invention mav be found useful in looking a single door The primary objectsof my invention are toprovide 'a simple, eflicient and conveniently operable mechanism for bolting one or more doors, and to furnish a construction in which the locking =mechanism for both doors of a pair, or for a sin le door, is connected in a simple but effective manner with similar locking mechanism of another door or doors, so that all of the doors of the battery or series may belocked and unlocked simultaneously, with the expenditure of a minimum amount of energy on the part of the operator.

To these and other ends, the invention consists in the novel features and combinations of parts to be hereinafter described and claimed. v

In the accompanying drawin Figure 1 is an elevation of a battery 0 four doors equipped with .my improvements, looking from the outside of the building. Fig. 2 is a horizontal section of Fig. 1, Fig. 3 is an enlarged view from-the inside, with parts broken away, showing portions of the two doors at the ri ht hand end of Fig. 2, and their associate locking mechanism, Fig. 4 shows on a still larger scale the locln'ng from the outside, the outside casing or covering panel bein ing double bolt sing in its locking position, Fig. 5 is a section on line 5-5 of Fig.

7 4, Fig. 6 is a view similar to Fig. 4. but

showing the swinging double bolt in its inin Fig. 3, looking omitted, and the swing-i operative position. Fig. 7 is a section on hne 7 -7 of F 1g. 4, Fig. 8 is a section on line 8-8 of Fig. 6, Fig. 9 is a section on line 9 -9 of Fig. 6, Fig. 10 is an enlarged section on hne 10 -10 of Fig.- 1, Fig. 11 is an enlarged section on line-11-11 of Fig. 1, Fig. 12 is a detail of one of the fronts, Fig. 13 is a deta l of one of the strikes, and Fig. 14 is a detail of the key.

In the drawings, I have shown my improvements applied to a battery of four swinging doors arranged in two pairs. A single bolt ng mechanism is associated with the mullion between the doors of one pair, in order to lock to the mullion the adjacent free edges of said doors. This mechanism for locking the doors of a single pair is connectedby means of suitable transmission 'mechanism to a similar locking mechanism associated with the isoperable by means of a suitable key, so that all four doors may be locked and unlocked simultaneously. However, it will be understood. from the following descri tion that the improvements are applicab e to more than two pairs of doors and that one or more of the bolting mechanisms empllfiyed may look and unlock a single door 0 y. InFigs. land 2 of the drawings, I have indicated the four doors above mentioned as A, E G and D respectively. The doors A, B swing toward each other and-constitute one pair, and the doors 0, D swing toward each other and constitute the other pair. The adjacent or free edges of the doors A are separated by a mullion E, and a similar mullion F is associated with the doors C, D. Boltin mechanism G is associated with the mullion E to lock the doors A, B, and-said bolting mechanism is connected by means of suitable transmission mechanism (denoted generally by reference character H) with similar bolting mechamsin I associated with the mullion F for locking the doors C, D. The mullions E, F and the upper part of the/door frame are preferably made in the form of hollow casings so that the bolting devices G, I and the transmission mechanism 'H may be housed therein and concealed from view. All of the doors are hinged to swing outward, as usual in school houses, theaters and similar buildings, so that when the locking mechanism of the doors.

bevel gears of the intermeshing pairs are all of the same size and hence it will be 'understood that as the shaft 41 associated with the doors 0, D is rotated in one or the other direction, by the actuation of the bolt, the connection between said shaft and the shaft 41 associated with the doors A, B will cause the latter shaft. to be simultaneously rotated to a corresponding extent, whereby the bolts of both locking mechanisms will be si multaneously actuated to lock or release all Both bolts will be moved simultaneously in the same direction and to the same extent. It is not necessary in all aspects of the invention that the two or more locking devices be interconnected by means of gearing, as any other equlvalent form of transmission mechanism may be employed. v

The improved mechanism has been found of special advantage when applied to the exit doors of school houses. At night, when the building is to be locked up, all *of the doors may be" locked simultaneouslyby a single manipulation of the key from the inside. In order to 'lock all of the doors, it is simply necessary to see that they are completely shut before the key is used for throwing the bolts, and door closers may normally hold the doorsclosed if desired. The locking mechanism is absolutely inaccessible from the exterior of the building, andno particularsafeguards against picking the locking mechanism are necessary. When the school house is opened for the dailyysession all of the doors may be released simultaneously by'a single operation of the key, and during school hours every door of theseries will be read to swing outward under the slightest push, so that free exit can be had in case of a panic.

The foregoing description is necessarily a detailed one in so far as it concerns the particular embodiment of my invention selected for illustration and description, and I have not attempted to describe the various modifications of the construction which may be adopted within the scope of the claims. One of the most obvious modifications is the omission of one of the locking arms of the double bolt, to make it a single bolt, in case one or more of the bolting devices is to lock a single door only.

What I claim is:

1. The combination of two doors mounted edges with recesses toengage the terminals of the respective arms, and a key insertible into said mullion to actuate said bolt; sub-' stantially as described.
